PacketiX VPN (formerly SoftEther) is Virtual Private Network (VPN) software that virtualizes network adapters, hubs, and switches. PacketiX differs from traditional VPN in that the hubs are virtual, so that a server can provide more than one isolated network for users to VPN into.

This SonicWALL signature identifies legitimate SSL traffic to any SoftEther (.softether.com) domain over any port.
